Extension Ring System Benefits

Extension rings provide a cost-effective solution for increasing electrical box capacity without the expense and labor of complete box replacement. They allow contractors to meet NEC/CEC box fill requirements while accommodating additional devices or complex wiring configurations. The modular approach enables precise capacity matching to specific installation requirements while maintaining code compliance and professional appearance.

Why Choose Drawn Steel Construction?

Drawn steel construction offers superior dimensional accuracy and structural integrity compared to stamped alternatives. The drawing process creates uniform wall thickness and eliminates weak points common in stamped products. This results in better alignment with existing boxes, improved mounting stability, and enhanced long-term durability. The natural steel finish provides excellent paint adhesion for custom color matching while offering inherent corrosion resistance in ordinary locations.
